Around the property
This summarizes expected hazards, past disaster records, designated hazard zones, city planning, the surroundings (stations, schools, medical facilities and more), population, land prices and transactions around the property, based on data from Japan's Ministry of Land, Infrastructure, Transport and Tourism. The position is estimated from the address, so it can differ from the actual lot near the edge of an area. Hazard areas and records shown are only those published by national and local governments; being outside a published area, or not finding a record, does not mean damage cannot occur. Please confirm details on the municipality's hazard map and in the explanation of important matters given at the time of purchase.
